**** BEGIN LOGGING AT Fri Apr 03 02:59:59 2015 Apr 03 06:33:01 Hello. I am having trouble getting my BeagleBone Black to connect to the Internet using an Edimax USB wifi adapter. I am using ubuntu 14.04, and already tried using wpa_supplicant, which shows a message saying it connected, but I still can't see the BBB from my router, or ping anything. I have read that RealTek's RTL8188CUS module is known to be unstable, and that a fix exists at https://github.com/pvaret/rtl8192cu-fixes that h Apr 03 06:35:53 Still, I suspect that that is not the issue with my BBB, as what I'm seeing is not unstable behavior, but no connection at all. Also, I tried to follow the instructions on that address, and I can't seem to clone the repository (I am asked for a username and password - as far as I can remember I didn't use to need that for cloning, but I am inexperienced with that and I could be wrong). Is there anyone here familiar with the wif Apr 03 07:11:06 Can anyone at least redirect me to another channel where I can get help? Apr 03 07:54:32 Hello, What is the DRI driver for beaglebone? Apr 03 09:19:49 lol @ GranTuringo Apr 03 14:07:20 hey guys Apr 03 14:07:23 one question Apr 03 14:08:14 Does anyone here have used the ESP8266 with the BBB? Apr 03 14:26:49 <_av500_> Nekhrist: have not heard it being mentioned here Apr 03 14:30:18 _av500_: "/ Apr 03 14:30:33 I've seen people using it on Arduino Apr 03 14:30:50 <_av500_> sure Apr 03 14:30:54 I thought it would be nice if we could use with the beagle Apr 03 14:31:04 <_av500_> well why could you not? Apr 03 14:31:11 <_av500_> out of the box it implemens an AT interface Apr 03 14:31:16 <_av500_> hook it up to a serial and off you go Apr 03 14:31:21 yeah.. why not? Apr 03 14:31:23 <_av500_> non? Apr 03 14:31:30 I am just waiting for it to arrive Apr 03 14:31:35 ordered from ali Apr 03 14:31:38 hey, got to go Apr 03 14:31:44 bye man Apr 03 14:31:50 <_av500_> yo man Apr 03 14:32:02 ta Apr 03 15:31:59 is there a uEnv.txt setting to change the boot order? Apr 03 15:39:03 <_av500_> like not boot from the drive that uEnv.txt is stored on? Apr 03 15:39:17 pretty much :-/ Apr 03 15:41:32 scenario… the case won't allow for pressing S2, so we want to trigger from software to allow the boot order to be changed so that we can flash vs. boot sequence always having an sd-card first approach Apr 03 15:50:16 <_av500_> so solder S2 closed Apr 03 15:50:21 <_av500_> then it will alsways boot from SD Apr 03 15:50:37 <_av500_> if there is SD inside, otherwise it should use emmc Apr 03 15:50:45 <_av500_> see the SRM for boot orders Apr 03 16:03:29 and probably the TRM too :p Apr 03 16:11:42 mwillbanks: what about setting the UUID inn uEnv.txt, or do you want choose the boot option at boot time? Apr 03 16:13:29 i have a 2 bbb boards (i think they are originals). the goal is to boot and run a webserver, as well as a touch screen user interface. There's too much information and I can't narrow down which way to go. Some direction please? Apr 03 16:14:43 root= on the SD's uEnv.txt should boot from the emmc even if there is an SD Apr 03 16:15:03 i don't want to have anything show up initially that says "beaglebone", and i don't want to have to start the user interface from a desktop environment such as X11 manually. Apr 03 16:15:59 so you want console only, or as default? Apr 03 16:16:18 <_av500_> no he wants x11 as default Apr 03 16:18:54 why just flash it with an environment, that starts in desktop, such as the latest (non-console) debian Apr 03 16:20:02 err, why not just? Apr 03 16:20:05 thurgood_: nice, however, we might not be able to control the SD which is the concern… it's more so, user puts in SD card, goes to software selects to flash device provided the SD card. at that point we'd reboot and flash Apr 03 16:21:09 ah, so you want to never boot from SD, not optionally boot from SD? Apr 03 16:22:21 precisely, and basically then force the software to change the boot order to something that will flash the emmc on reboot if it a flag has been triggered Apr 03 16:37:51 sorry, i asked this a while ago, is there a chip i can get to make the bbb wireless, rather than usb? Apr 03 16:38:25 preferably not a massive cape, i'm trying to keep the size down Apr 03 16:46:40 define "massive" Apr 03 17:54:00 so it looks from the last discussion on this, that right now fw_printenv and fw_setenv do not work when running from emmc? Apr 03 17:54:18 basing it off of the following topic: https://groups.google.com/forum/#!topic/beagleboard/ZXO9zU_raBk Apr 03 18:29:58 mwillbanks .. I think there is a config option to where it points Apr 03 18:30:55 I remember looking at building it for an arm board, as out-of-the-box it doesn't work without some file/option Apr 03 18:49:27 what are the steps i need to take to get a beaglebone black to boot to a gui without any beaglebone logos or desktop environment? Apr 03 19:17:55 Hmmm that would have to do with grub/grub2 if I remember Apr 03 19:24:47 Currently I think i've bricked my bbb trying to update to debian. Apr 03 19:26:23 i just get d2 on d3 on, all off, d3&d5 on , all off, repeat Apr 03 19:29:10 The best thing is to test with an SD card booting first Apr 03 19:30:24 will boot from sd card. Apr 03 19:31:05 i guess i should have phrased it "rendered the emmc unusable" Apr 03 19:32:51 Hmmm you should be able to fix the emmc device. Apr 03 19:33:30 you should be able to boot an SD card and it should be able to fix the emmc device I can't remember where I was reading about that. Apr 03 19:33:58 jnewt .. you can compile a kernel without the beagle logo .. and if you want a console environment, I recommend RN's minimal debian image at eewiki.net Apr 03 19:34:34 hmm damnit gotta rebuild a kernel .. missing hda_audio module :/ Apr 03 19:34:53 GenTooMan: how do i tell what state it's in from the LED's? is there a key somewhere? i don't see it in the datasheet. Apr 03 19:35:27 jnewt .. there is no 'code' .. they have different functions as specified in the SRM Apr 03 19:35:47 eg. 'disk' access .. heartbeat .. power, etc. Apr 03 19:35:48 section 6.6 talks about the User LEDs, but nothing to tell me where I am right now. Apr 03 19:36:05 no .. you will have to work out from which LED .. what is/is not happening Apr 03 19:36:21 jnewt .. do you have a serial debug cable? Apr 03 19:36:42 i have an ftdi cable somewhere. Apr 03 19:36:48 if not, I recommend you get one .. they're only a few $/E/£/etc Apr 03 19:37:00 needs to be 3v3 compatible .. otherwise should be good Apr 03 19:37:15 brb Apr 03 20:01:11 veremit, ok, found my ftdi cable, says ttl-232R-5V, no good? Apr 03 20:01:34 correct, dont' use that one. ;) Apr 03 20:04:10 Yes 5V on the signals will cause the protective diodes to activate and cause a failure :D Apr 03 20:07:42 i think i just figured out why it wouldn't work. i pulled out the network cable and it booted from the angstrom (which would have to be on emmc) Apr 03 20:08:59 then i plug it back in and i have internet. Apr 03 20:09:14 ok, so step one, figure out how to boot with cable plugged in Apr 03 20:15:11 the debian image says it's compatible with all versions. does this maybe mean compatible with the exception that you can't run it from the on-board memory? is it too big? Apr 03 20:24:57 jnewt .. there are two images depending on board revision .. one is 2gb the other 4gb Apr 03 20:25:23 this matches the size of the emmc .. so if your board is rev.c use 4gb otherwise, use the 2g one Apr 03 20:30:51 ok, so i need to find a 2gb debian image, and rebuild the kernel to remove the beaglebone image from boot. is there step by step procedure for that somewhere? best i've found is a google group reply that i can't really understand. Apr 03 20:33:36 and there's this: https://eewiki.net/display/linuxonarm/BeagleBone+Black, but it is build for people who are running linux on both their beaglebone and their regular computer. which is not me. do i need another computer running linux? Apr 03 20:34:39 jnewt .. you can 'spin up' a virtual machine that is linux . using virtualbox or vmplayer Apr 03 20:37:48 Hi there, I am trying to figure out how to install debian jessie (RC2) on BBB (armhf: https://www.debian.org/devel/debian-installer/), but i cant find any instructions how to boot into the debian-installer (i dont have tftp). Is the iso image applicable to BBB? Apr 03 20:47:27 tty0: there should be an appropriate debian flasher here http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Jessie_Snapshot Apr 03 20:55:00 hi, electronics noob here. Is it safe to power beagle via 12v/2a power supply (barrel connector)? Apr 03 20:59:57 chatmasta, if you don't mind a one time magic smoke and a fire works shows... Apr 03 21:00:20 KotH: hi, how are doing Apr 03 21:00:50 rcn-ee: That is what I figured. What is more important when considering safety of power supply? voltage, amps, or watts? Apr 03 21:01:51 in 90% cases voltage first .. then current/amps .. that determines watts Apr 03 21:02:11 chatmasta, get a 5volt 2amp power supply and it'll cover 99% of what you can push/connect to the bbb.. Apr 03 21:02:54 veremit: unless they work with LEDs 90% of the time ;) Apr 03 21:03:09 ds2 : :P Apr 03 21:03:10 Yeah, issue is I need to wait a few days for that so I'm stuck with what I have. Currently powering via a "5W" usb power brick. but it also says "5v == 2a" Apr 03 21:03:29 5w != 5v@ 2a Apr 03 21:03:35 5v * 2a = 10w Apr 03 21:03:39 yeah that's what I figured and why I am confused. Apr 03 21:03:59 It says "5W" in big letters on the back, and in small text says "5.0V = 1A" Apr 03 21:04:07 the equals sign is a solid line on top, dashed on bottom Apr 03 21:05:02 I am successfully powering a wifi AP with this but need to also power usb hub + 3g modem Apr 03 21:05:04 ds2: you have a point .. a section of electronics does require constant-current these days .. leds are just one case Apr 03 21:05:30 the symbol for 'DC' is a dotted line over a solid line :p Apr 03 21:05:48 becareful about reading watt ratings Apr 03 21:06:00 ok. I am just not going to mess with it since it seems to be working. I'll wait for the proper power supply to arrive haha Apr 03 21:06:06 some folks like to confuse things and write the watts it consumes Apr 03 21:06:15 ds2: generally just ignore them completely ;) Apr 03 21:06:35 so you can indeed have a power supply that can deliver 5V @ 1A and draw 10W. (50% efficient) Apr 03 21:06:41 until you start doin dissipation calculations :\ Apr 03 21:07:17 5W isn't too bad...that's like an incandent nightlight Apr 03 21:07:31 ah you just reminded me .. Apr 03 21:07:57 if you think about the overall process, 50% is not completely out of line. for a US setup - Apr 03 21:08:35 120V => 9V ish is an xformer. there is losses there due to magnetization current, and wire resistance Apr 03 21:09:02 9V provides enough headroom to use a linear regulator along with a diode drop Apr 03 21:09:05 How about iphone usb power brick? 5.2v/2.4a Apr 03 21:09:35 thought the fruit stuff use nonstandard voltages and crap? Apr 03 22:21:42 hello Apr 03 23:03:38 do i need to recompile all of an image from source to just remove the beaglebone splash screen at boot? is there no better way? **** ENDING LOGGING AT Sat Apr 04 02:59:58 2015
